Claims (3)
- 逆止弁を内部に備えた逆止弁ユニットを、既設給水配管の途中において交換可能に取り付ける逆止弁の取付構造であって、
上記配管に対して着脱可能な収容管は、その内部に前記逆止弁ユニットを一方向から挿入することで収容可能であり、かつ、一方向に押し込むことで前記収容管から取り出し可能に構成され、
前記逆止弁ユニットはその側面から鋭角に突出する弾性爪を有すると共に、前記収容管の内面には前記弾性爪と係止して内部に収容する前記逆止弁ユニットの一方向への移動を禁止する溝が形成されており、
前記収容管に対して連結される固定管の端部が前記収容管に収容された前記逆止弁ユニットの周縁端部に当接したとき、前記固定管の端部と前記逆止弁ユニットの前記溝に係止する弾性爪とによって弾性的に挟持して、前記溝による前記逆止弁ユニットの移動禁止方向とは異なる方向への前記逆止弁ユニットの移動を禁止して固定することを特徴とする逆止弁取付構造。 - 請求項1に記載の逆止弁取付構造を、既設給水配管途中に設置される止水栓の伸縮ユニオンに設けたことを特徴とする逆止弁取付構造。
- 請求項1に記載の逆止弁取付構造を、既設給水配管途中に設置される配管継手に設けたことを特徴とする逆止弁取付構造。
